Wrong date on Docker Addons

Hi there, some of my users (who use hassios) have a wrong date on my custom docker addons.
I use homeassistant alpine image for base build:

  "build_from": {
    "aarch64": "homeassistant/aarch64-base:3.12",
    "amd64": "homeassistant/amd64-base:3.12",
    "armhf": "homeassistant/armhf-base:3.12",
    "armv7": "homeassistant/armv7-base:3.12",
    "i386": "homeassistant/i386-base:3.12"

It appear as variable TZ is not used during container building.
I’m using ubuntu with docker and supervisor but i don’t have this issue
